Background. Chronic kidney disease (CKD) is a global public health problem worldwide, associated with an increased risk of cardiovascular and all-cause mortality.
Objective. Identification of the regional features of the causes and rate of progression of CKD in the northern territory.
Material and methods. The data of the registry of 484 patients of the Nephrology Department of the Komi Republican Clinical Hospital for 2015–2018 were used; there were 231 (47.7%) men and 253 (52.3%) women. The mean age was 58.8±15.8 years.
Results. The number of patients with 1 visit – 314, with 2 or more visits – 170 patients. The mean glomerular filtration rate (GFR) was 30.1±19.3 ml/min/1.73 m2. Distribution by CKD stages: stage 1 CKD – 1.2%, 2 – 5.6%, 3a – 13.6%, 3b – 12.4%, 4 – 26.4% , 5 – 26.6%. The main causes of CKD: tubulointerstitial nephritis (21.5%), diabetic nephropathy (16.7%), chronic glomerulonephritis (15.7%), hypertensive nephropathy (12.0%), the diagnosis is not defined (12.8%). The average decrease in GFR was 3.99±2.7 ml/min/1.73 m2 during the year of follow-up. In patients with stage 2 CKD, GFR increased by 8.4 ml/min/1.73 m2 per year, with stage 3 CKD - a decrease by 0.13 ml/min/1.73 m2 per year, with stage 4 – decrease by 5.17, with stage 5 – decrease by 6.8 ml/min/1.73 m2 per year (p=0.034). A direct association of the rate of impairment of renal function with the level phosphate, urea, potassium, proteinuria, ESR levels, and an inverse association with the o hemoglobin, GFR levels was revealed. The most frequently prescribed drugs for the treatment of patients were angiotensin-converting enzyme inhibitors (32.4%), calcium channel blockers (47.5%), statins (36.4%), β-blockers (35.1%), diuretics (24, 6%), antiplatelet agents (39.9%).
Conclusion. Maintenance of a CKD registry allows to identify regional features of CKD and assess the rate of progression of CKD.
